HOMER W. CASE, OF POUGI-IKEEPSIE, NEW YORK.

SIFTER.

Specification of Letters Patent.

Application filed August 28, 1912.

Patented Feb. 1'7, 1914:. SeriaI No. 717,536.

To all whom it may concern:

Be it known that l, HOMER V7. CASE, a citizen of the United States, residing at ll oughliieepsie, in the county of Dutchess and State of New York, have invented new and useful improvements in Sifters, of which the following is a specification.

This invention relates to sifters and more particularly to that type which are specifially adapted for sifting dry insecticide or like material over the plants.

One of the principal objects of the invention is to improve upon former Patent No. 9341,2233, granted September 1% 1909, which cannot be used successfully and accurately upon small plants and the amount of discharge cannot be regulated in any way cxcept by governing the turning of the receptacle by the operator.

The obj ectof this invention therefore is to provide a sifter which may be conveniently used upon small or large plants and having such construction that the discharge may be conveniently governed in accordance with the quantity desired to be expelled and with the material being used.

llurther objects of the invention will appear as the following specific description is read in connection with the accompanying drawing which forms a part of this invention and in woich:

lligure 1 is aside elevation. Fig. 2 is a vertical sectional view thcrethrough. Fig. 3 is a bottom plan view. Fig. 4t is a detail showing the bottom closing plug in position to out off discharge through the bottom of the sifter.

Referring more particularly to the drawing 1 represents an elongated substantially cylindrical receptacle having a cap limit rib 2 formed adj aeent its upper edge and being provided with a closing cap 3, the receptacle is supported and operated by a bail shaped handle t and has its lower end provided with an outstanding circumferential flange and closed by a foraminous bottom 5 which is journaled or otherwise secured to the receptacle and forms in effect a continuation of the foran'iinous portion 6 at the lower end of the receptacle. When the sifter is used upon very small plants it is desirable that the perforations in the portion 6 be entirely closed and the perforations in the bottom 5 used. To cut off the discharge through the perforations in the portion 6 or to regulate the discharge through said perforations a sleeve 01' collar 7 surrounds the receptacle 1 and is slidably mounted thereon being held in adjusted position by means of friction. The outstanding flange at the lower end of the receptacle forms a stop to prevent the regulator frame from being casually detached. The preferred type of regulator is a split paste board ring held in engagement with the re ceptacle by means of elastic bands 8 as shown. As the vines continue to grow the side perforations can be readily exposed to a degree necessary to produce proper sprinkling of the plants when these vines or bushes get very large and form a continuous row, if the bottom is left open and the siftercontinucusly operated there would be too much material distributed in the center of therow thereby causing waste, to avoid this a plug 9 of paste board or other suitable material is furnished with each sifter and may be placed upon the bottom to entirely close the perforations therein. The side perforations may then be regulated by shifting the collar 7. As will be readily understood this collar may be of any suitable material but paste board is preferably used on account of the fact that it hangs close to the recep tacle and is not affected by being dented which would be the case if metal were used.

The device is operated for either small or large plants in a similar manner by holding the receptacle over the plants and resiliently twisting or turning same in opposite directions.

lVhat is claimed is:-

1. The herein described siftcr comprising a vessel having a foraminous bottom and also having the lower portion of its walls perforated, and further provided with an outstanding stop flange at its bottom, a split sleeve extending around the wall of the vessel, and means on said sleeve to cause the sleeve to frictionally engage with the vessel and hold the sleeve in adjusted position, the sleeve being adapted to be moved over or removed from the perforated lower portion of the wall, for the purpose set forth.

2. The herein described sifter comprising a cylindrical vessel having a foraminous adjusted position, the stop flange prevent- 1ng casual detachment of the sleeve.

In testlrnony whereof 1 air; my slgnature in presence of two Witnesses.
